EDIT:
To me seems she has quite dark head and quite contrast light eyebrows. The "problem" is that the head feathers aren't only dark-colored, but there are lighter tips etc, so in different position she may look different, if she is looking up then she may look more "white-head", plus the lighting plays own role.

on this pic is the same bird (both are renandeli's snapshots)

The male seems to have lighter head. I didnt find sitting-standing pictures of him (where can be sure its same bird) to compare. One picture and probably a male (my nonprofessional opinion only)

The head feathers look lighter, His "pants" are lighter too ....though its more his behavior what makes me think, its he.viewtopic.php?p=37550#p37550

To me seems, the male spotted eagle can (has skills) incubate, he may replace a female some time, but his priority is to bring food, he doesn't sit on eggs hours and hours (different compared with WT-eagle)
